If you’ve run out of beer and for some awful reason you cant go get more. What could possibly taunt you more than a beer filled USB drive? I swear it would not surprise me in the least to see a news bulletin somewhere, where a guy decided to try to suck the beer out of his USB drive. Itd likely start with one guy either daring or offering up some small fund to do it, like a dollar. It really wouldn’t take much for someone to do it. Well luckily there are no links to actually purchase this USB drive, instead it is just an example of all the cool things a certain company can do with USB drives.The company can not only fill your USB drive with liquid but add little objects to the mix. Like a car for a racing company. Basically, those cheesy pens that the top of them was filled with liquid have now been replaced with these USB drives. Well, I suppose it had to happen eventually. If you feel the need to create liquid filled USB drives with your company name stamped on them just follow the link to find out more info.

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.
Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze.
First sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk.
